Hi Emmanuel, Thanks for you mail. Indeed I believe that the path extensions are already covered by the regex syntax [1]; did you already try it out?
Cheers, Christian [1] http://docs.basex.org/wiki/RESTXQ#Paths Am 09.07.2017 17:23 schrieb "Emmanuel Chateau" <emchat...@laposte.net>: Hallo Christian, As you know I’m really interested by this issue. On this topic, I was wondering if it could be possible to implement something to deal with path extensions in RESTXQ. It would then be possible to perform later transparent content negotiation in the function. For exemple : ```xquery declare %restxq:path('/path/{$path}') function works() { ' ' } declare %restxq:path('/path/{$path}.json') function works() { ' ' } (: basex shouldn’t consider it like a duplicated path :) ``` And a way to get the file extension in the path as a parameter. I’m not sure that it is already possible with regex in path. ```xquery declare %restxq:path('/path/{$path}') function works() { ' ' (: something to get the file extension back in a variable to do reason :) } ``` Best regards, Emmanuel > Le 9 juil. 2017 à 11:10, Christian Grün <christian.gr...@gmail.com> a écrit : > > Hi Omar, > >> Thanks for the answer.
